The U.S. Government has recently issued seven major studies that together put forth a comprehensive blueprint for major global changes in U.S. national security strategy, defense plans, and diplomacy. These seven studies are brought together in this illuminating book, which portrays their individual contents and complex interrelationships and evaluates their strengths and shortfalls. It argues that while these studies are well-written, cogently argued, and articulate many valuable innovations for the Department of Defense, Department of State, and other government agencies, all of them leave lingering, controversial issues that require further thinking and analysis as future U.S. national security policy evolves in a changing and dangerous world. For all readers, this book offers a quick, readable way to grasp and critique the many changes now sweeping over the new U.S. approach to global security affairs.
